vortex street

(General Physics) a regular stream of vortices or parallel streams of vortices carried downstream by the flow of a fluid over a body. These are sometimes made visible by vapour condensation as in the vortex trails from the wing tips of an aeroplane. See also Kármán vortex street, vortex shedding

As the frequency of the vortex street in a vortex meter and of the secondary rotation in a swirl meter are each directly proportional to the volumetric flowrate of the fluid, there is no need to compensate for changes in pressure, temperature or density.

Full steam ahead for quality energy management: With the emphasis now very much on finding ways to manage energy more responsibly, both for economic and environmental reasons, using steam more efficiently is vital to reducing costs and boosting green credentials

In the lab, I used a cylinder to simplify turbulence and generate an organized pattern of eddies, called a Karman vortex street. This vortex street is the name given to the consistent pattern of eddies that spin off in a line downstream of a cylinder.

The Tao of fishing currents: in 571 B.C. the Chinese philosopher Lao Tzu's observations of the natural world led him to the concept of wu wei, which literally translated means "to go with the flow." Taoists call it "effortless action." Fish also go with the flow in some surprising ways

My overwhelming first thought was to try and produce a work with movement to mimic the von Karman vortex street. That said, how to end up with such a work seemed like a huge if not impossible task.
